The DB crash doesn not mean a backend crash. It means the lost of 80% of
the tables of the database.
here is the scenario:
1: I initiated a "drop table mytable" operation.
2: It started to took 15 minutes, then I decided that laybe users were
using this table
3: I killed the postgresql process.
4: I opened pgsql
5: I listed the tables ..."mytable" still there
6: I issue a drop table again, after having restarted the backend (not
properly...a "kill" then a "postmaster start ")
7: the drop table doesn't work, even if the table "mytable" still appears.
8: I issue a "vacuumdb"...take hours, and stays blocked on my problematic table
9: I re-killed the back-end.
10: I started the DB: only four tables left...mytable and a lot of others
have disappeared.
